cLENcHEa i-m RELEAsme TooL.

Be it known that we, JOHN E. GLronnar and ALFRED L. SWIGERT, JrL, citizens of the. United States, residing at Indianapolis, inI' the county. of Marion and State of Indiana,

, have invented new and'nseful Improvements in Clen'cher-Tire-Releasing Tools; and we do; declare. the following to be a full, clear, and exact description of. the invention, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of this specification.

This invention relates to tools'for releas ing pneumaticv clencher tires from vehicle= wheels, especially the relatively large and strong tires that are commonly used on automobile-wheels, the purpose :of releasing the tires being to permit repairs 'to be made thereto, or to replace worn-out tires with new ones, or to perm t repairs to be made to other parts of the wheels; and the invention has reference particularly to 'tools that may be hooked-to one side of the metallic rim ofthe fellyto which the 'flanged edges of the tirecasing are directly connected, the tools having parts that are adapted to force the flanged edge of the casing at the opposite side of the rim loose, so that thecasin'g maybe-readily removed from the rim.

The object of the invention is" to provide a tire-releasing tool that will have a' wide range of adjustment in order to be able to release tires of considerably difierent' diametrical dimensions, and to provide a simple, cheaplyconstrncted, and highly-powerful tool for releasing tires, and which willbedurable and economical inuse.

With the above-mentioned and minorobjects in view the inventionficomprise's a novel tire-releasingtool having compound leverage and consisting of a yoke, a lever anda holdingjaw pivoted to opposite sides of the yoke,

and atraveling jaw pivoted to theholdingjaw and also to the lever; and'the invention consists, further, in the novel parts and comb and a clencher-tire casing, omitting the air tube, shown in cross-section, dotted lines inv Specification of Letters Patent.

dicating the different positions of the parts of the tool and casingwhen the casing is released from' one side of the wheel-rim; Fig. 2, a side view of the tool v ewed in reverse d1 rection and ad usted to operate on a tire of spective view of the lever of the tool. 1

. Similar reference characters in the different figures .of the drawings designate correspond- 1ng elements or features of the invention.

The tool comprises a yoke that is composed offa body part .A having lateral arms 0 and -l):project'ing from its ends, the whole being.

approximately U- shape and adapted to span the 'wheel fe lly and rim thereof without inter-' fering contact therewith. A A holding.- jaw comprises a bodyD, havingaprojecting finger E with a curved inner side-o formed on one end to engage the wheel-rim, and having a lateral am i. F formed on the other end thereof,

thefinger and the arm both extending from one side of the body, and the body is connected near the finger to' the end part of the arm B of the yoke by means of a pivot 12. A traveling jaw com rises a body Gr, having at one end thereof al end connectedto the end of the arm F of the maximum sectional diameter, the lever being broken away; Fig-3, an end view of the traveling aw; and Fig. 4, a fragmentary perateral arm H, that has its holding jaw by'means of a pivot c', and an arm I is formed on the opposite end of the body G ofthe traveling jaw, the arm I having lateral projections d and d at its end so as to form a relatively broad end face e for thearmto present to the rubber casing of the itre, .the end e being approximately op osite to the end of the finger E. A lever has apivothole ,5 in one end thereof, this end being connected' to the body G of the traveling jaw near the arm I by means of a pivot f, the same end hav ng a short lateral ear K, having a pivot-hole 6, and is connected to the'end C of the yoke by means. of a pivot g, whichis suitably near to the pivot f. The arm or handle of the lever J may be moved close'to the arm-C of the yoke to increase the space between the finger .Ennd the arm I to the maximum, and a movement of the lever in the o posite direction will decrease the space rapid y to the minimum degree.

In ractical use the tool is to be placed with t e yoke extending across the inner side of the felly h, with the finger E in engagement with one side ofthe metallic rim '1; and the.-

moved so as to cause the arm I to force the flanged edge 70 of the casing of the tire out of engagement with the rim L toward the edge 7 and thenaway from the rim entirely, so that the edge lr' may be easily pried or drawn out laterally over the side of the rim to gain access to the interior of the casing. The tool may be 'found ing the edge k of the casing.

Having thus described the invention, What is claimed as new is 1. A tire-releasing tool comprising a yoke formed of a body part and two lateral armsattached rigidly to the body part, the yoke being a proximately U shape, a holding-jaw pivote to one of the arms of the yoke, a lever pivoted to the other one of the arms of the yoke, and a traveling jmv pivoted to the lever and also to the holding-jaw.

2. A tire-releasing tool eomprising a rigid yoke, a l 'oldingjaw'comprising a body part aving a projecting rim-engaging.iinger on one end and a lateral arm on the opposite end thereof, the body part near the finger being pivoted to the yoke, a lever pivoted to the yoke, and a traveling jaw pivoted to the lever and also to the arm of the holding-jaw. 3. A tire-releasing tool comprisimg a rigid yoke, a holding-j aw pivoted tothe yoke,- a lever having a relatively short lateral ear near an end thereof which is pivoted to the yoke, said lever end being relatively short, and a traveling jaw pivoted to the holding-jaw-and also. pivoted. to. said lever near to said ear.

4. A tire-releasing tool comprising a rigid yoke, a holding-jawpivoted tothe yoke, a leshort end part of the ver pivoted near an end thereof to the yoke,

= and a traveling jaw having a body part pivoted near an end thereof to the end of the lever near which the lever is pivoted to the yoke, said body part having a rigid lateral arm 011 the end thereof near its connection 'with the lever and a'lateral arm on the opuseful also in replac- 5. .A tire-releasing tool comprising a yoke having a body part and two lateral arms attached rigidly to opposite ends of the body part, the yoke being approximately U shape and rigid throughout, a holding-jaw comprising a body part having a laterally-proj ectinq rim-engaging finger on one end and a latera arm body part near the finger being pivoted'to an arm of the yoke, a lever having a relatively short ear attached rigidly thereto near an end thereof and pivoted to the other one of the arms of the yoke, said lever having a relatively short end part, and a traveling jaw having a body part pivoted near an end thereof, to the relatively shortend of the lever near said ear thereof, said body part having a rigid lateral arm at one end thereof extending to and pivoted to the end of the arm of the holding-jaw, the opposite end of said body part of the traveling jaw having'a tireengaging arm attached thereto.

6. A tire-releasing tool comprising a U- shape yoke having a body and a plurality of rigid arms, a holding-j aw having a body part pivoted to one of the arms of the yoke and provided at one end thereof with a rigid arm and at the opposite end thereof with a rigid rim-engaging finger, a lever having a rigid lateralear pivoted to another oneof the arms of the yoke and having also a relatively short end part, and a traveling jaw having a body part pivoted near an end thereof to the short end part of the lever and provided at its opposite end with a rigid arm pivoted to the arm of the holding-jaw and having also a separate rigid arm provided with lateral projections at the end thereof for engaging atirel In testimony whereofwe aflix our signatures in presence of two witnesses.
